Chain final-drive systems are by far the most common. In this system, a sprocket installed to the result shaft (i.e., the shaft in the tranny) is linked to a sprocket mounted on the trunk wheel of the motorcycle by a steel chain. When the transmitting turns the smaller front sprocket, power is certainly transmitted along the chain to the larger rear sprocket, which in turn turns the rear wheel. This kind of transmission system in automobile must be lubricated and modified, and the chain Stainless Steel Chain stretches and the sprockets use, requiring periodic replacements.
Belt drives
Belt drives are an alternative to chain drives. Early motorcycles frequently used leather belts, that could be tensioned to provide traction utilizing a spring-loaded pulley and hand lever. Natural leather belts often slipped, specifically in wet weather, so these were abandoned for various other materials and styles. By the 1980s, developments in materials made belt final-drive transmission system in automobile practical once again. Today’s belts are made from cogged rubber and operate quite similar way as metal chains. Unlike metal chains, they don’t need lubrication or cleaning solvents.
Shaft final-drive
Shaft final-drives are occasionally used. This transmission system in automobile transmits power to the rear wheel with a drive shaft. Shaft drives are popular because they are hassle-free and don’t need as much maintenance as chain-based systems. Nevertheless, shaft drives are heavier and sometimes cause unwanted motion, called shaft jacking, in the trunk of the motorcycle. The additional components that produce a motorcycle a motorcycle are section of the chassis.
Advantages and Disadvantages
The major advantages of shaft-drive are lower maintenance and running costs, and cleanliness. Chain-drive bikes need their chains adjusting frequently and they could be costly to replace when they wear out.
They want lubricating often, specifically in bad weather, which can be messy and inconvenient. And chain lube increases the running costs.
Shaft-drive systems are completely enclosed and so are unaffected by the elements and only need periodic oil changes.
The disadvantages of shaft-drive are that it is a lot heavier when compared to a chain and absorbs more of the engine’s power before it reaches the trunk wheel
Compared to a Chain system
A shaft-drive may also change the action of the trunk suspension – when the throttle is opened and closed quickly the bike can rise and squat since the shaft is wanting to “climb” the cog on the trunk wheel.
Power Transmission
The chain drive system comprises of two sprockets, one on the gearbox and one on the rear wheel, that are linked by a chain.
In a shaft-driven transmission program in automobile, a shaft connects a gear inside the gearbox to some other gear inside a hub on the rear wheel.
When the 
engine is sparked, power is transferred along the chain or shaft to the rear wheel, and the bike moves forward. Either program is commonly referred to as “final drive,” as it is the last set of components employed to provide power to the rear wheel.
Some producers, notably Harley Davidson, have used belt drives on a few of their model line-ups. BMW, Kawasaki, and Suzuki also have attempted the belt drive system.
